TPS65146 datasheet

 

Description

The TPS65146 offers a very compact power supply solution designed to supply the LCD bias voltages required by TFT (Thin Film Transistor) LCD panels running from a typical 3.3 V or 5 V supply rail.

The device integrates a step-up converter for VS(Source Driver voltage), a positive charge pump regulator for V GH (Gate Driver High voltage), a logic voltage rail using an integrated LDO and a VCOM buffer driving the LCD backplane. In addition to that, a gate voltage shaping block is integrated for V GH , modulating the signal (into V GHM) with high flexibility by using a logic input VFLK and an external discharge resistor connected to RE pin. Also, an external discrete negative charge pump can be set using the boost converter of the TPS65146 to generate V GL (Gate Driver Low voltage).

The integrated reset function together with the LCD discharge function available in the TPS65146 provide the signals enabling the discharge of the LCD TFT pixels when powering-off. The device includes safety features like overvoltage protection (OVP), as well as thermal shutdown.

Features

1. 2.5V to 6.0V Input Voltage Range

2. 16.5V Boost Converter With 2A Switch Current

3. 650kHz/1.2MHz Selectable Switching Frequency

4. Adjustable Soft-Start for the Boost Converter
